To all whom it mag concern:

1 Be "it known that I, IRVIN RosnNrnLn, a citizen of theUnited States, residing at New Yorkcity, Bronx, county and State of New York, have invented new and useful Improvements in Change-Making Machines, of whichthe following is a specification.

- This invention relates to a machine of novel. construction for delivering any desired amount of change, up to one dollar,

certain theaggregate value of the diflerent pieces of coins released. The machine is provided with preferably one hundred keys inarked successively from 1 to 100, and so connected to the ejecting mechanism that by depressing any one-v of said keys, the

5 amount ofchange indicated thereon will be it common; ontlet,,21.

liberated, In this way the manipulation of the machine is facilitated and-errors, owing to miscalculation, are prevented. i

In theaccompanying drawings: Fi ure 1 is a front elevation of. my improved change making machine; Fig. 2 a vertical longi- ;tudinal;section on line 2--2, Fig. 1; Fig. 3 -a longitudinal section on line 33, Fig. 2, showin the' sliding .plates partly broken away; ig. 1 a cross section 'online 4 4,' Fig. 2;..F 1g. 5 a vertical section of the first penny ma azine; Fig. 6 a similar section of the secon -penny.magazine; Fig.- 7 a cross [section on 1ine.-7--7, Fig. 5, and Fig. 8 a

. similarsection on line 8-8, Fig. 5.

- The frame 10 of the machine is preferably so supported upon legs 11, as to have a rearward dip. At its front, frame 10 is provided-withpreferably seven coin maga- .jzines '12, 13-, 14, 15, 16, 17, 18, of which magazines 12, 13-are both adapted for the reception of stacks of one-cent pieces ;.maga- J-fzine' 1f]: is adapted forthe reception of :nickels; magazines 15 and 16 are both adapt-- fiiafor dimes-,while magazines 17, 18 are -..respeetively. The coins are supporte I 1n each magazine upon a base plate or rest 19 having a concave front edge over which then-coins are adapted to be pushed, by the mechanism-hereinafter described, ,so as to fall, into; ,a. ,chute' 20 that extends infront of ;all.,; the .niagazinesand discharges all the ,gCOlIlS. .,si nultaneously released,.; through a The ,means fgr e ecting coins consist- -1nagazine 13 of preferably eight spaced superpdsedg'platles ONE-HALF T0 cnannns r eusrnv wmrns, or WO0DHAVEN,-- NEW YOBK.... 3'

The plates are of rectangular 30 projecting inwardly from p'osts"*31" s"e- -allel to each other and having a slight rearshape and are slic ably supported upon pins cured to the inner sides of' the machine frame. EflClPJlfltQ 1s provided-at its for-{* marked respectively 32," 34, 36, 37, 38, 39, such ejector enter ng one of-[t'he magazines 12 to 18, with the-exception of ejectors 32 and 33, which bothenter nmga zine 12. That is to'say, ejector 32 of plate 22, as well as ejector33 of plate lioth enter the first penny magazine 12 througha slot formed in the back-wall thereof directly posed upon ejector 33, while the-lattew in turn, moves along the base 'plate"-19 of 'the magazine. Each of these e ectors isw'if'a thickness adapted for the ejection ofa single sing e penny is discharged, while .whenboth ejectors are advanced, two'een'ts' are simultaneously discharged. "In order to holdba'ck the coin alined withto ejector 32, when 'a above'its base plate 19. Ejector 32 is supercoini so that when ejector '33 is advancedv single penny only is de iveredby ejeetor' 33f' said top ejector is providedwitlr a curvedclaw 40 that partly encompasses itsc01n, b11 t will release the same uponthe: advance of ejector 32. ector. -34 of plate 24 enters 19, and in' like manner ejectors 35, 36, 37, 38, 39 enter, respectivel the-.ma azines d4, 15, '16, 1'2", 18. As wil be readily understood, the several coin ejecto1's'(with the irectly above its' base plate 3 exception of the superposed ejectors 32,-. 33)

are arranged side by'side, each ejector entering one ofcthe magazines while clearing-stall theother magazines. .The thickness ofl each ejector is such that. it will engage a1sin'gle coin,: with this exception, that e ector 34 is T l of double thickness, so that -.-i't=' wil1 51111111- tarieously dischargetwo cents. e-Ais )lates22 V to 29 are arranged above on'eianot ier, and as I theae ectors extend forward from their respective plates, such ejectors willassume a step-shaped relation and: the base plates of thefvarious magazines alpngnwhich thezejeetors. move, are correspondingly 1; stepped,

(Figs-.1 and 4.)" To reventa'IL'eXceptingtLie:hottbmcoins, from. eingpushed out of the magazines, the

' bearing character which indicates the tamountlof change it will eject.

is made in the form ofa two-arm lever, the ten' keys of every transverse row being ful-.

partitions between the latter are provided along their upright edge s with'laterally cirtend ng flanges 42 notched at their bottom as In order to actuate plates 2-2"'29, there are employed, preferably, one hundred keys 44, each of which is designed to deliver a' different amount of change from one centup to one hundred cents, so that by manlpulatin the proper key, the change desiredwill he obtained. The keys are referably arranged in'ten parallel rows, eaca containang tenkeys, and eachkey has afinger-piece Each key crumed upon a common shaft 'fi jextending across frame, 10, so that for the ten rows of keys, ten shaftsdai are employed. The

keys of every row are-separated from each other by spacing collars 46 mounted on their I ;f shaft-45,.andtightened up by a coiled spring 47. The relative arrangement of the keys is are staggered, with those mounte ad oining shafts, by which arrangement spaceis economized and an increased sweep such, that those mounted on'any one shaft on the for the'key-is obtained, It is preferred to hang each key in such a manner upon ts shaft'45,.that iti can bev readilyremoved therefrom, for which purpose it is provided fwith-a fork 48 straddling such shaft. Fingers 49 extending forwardly from the upper arms of the'nine rear rows of keys lhfind a'bearing-on the collars; 46 0f the immediatelyvpreceding rows and thus support the keys in their normal posipion. The keys of the frontro'w are similar y sustained by an 4o abutting flange50 of frame 10.

Each of the keys those specific plates 22 to 29 which jointly or severally eject the quantity of changeiir,

dicated' upon the finger-piece of said key.

'Tothis efi'cct,.the lower arm of each lover I '44 extends through the entire number of plates 22 to 29, which are slotted for the accoin'inodatmn of saidJarin. 'plates'22'-29 are made intwo vdlf'fercnt The slots in length's,sl-1o.rtcr slots 51 bcingprovided for those levers which are to take the plates alon while" lon er slots 52 are )rovided for those levers which are to clear the plates The position" of the short slots 51 is such thatt h'eir front periineters arein substantial'contact with the forward edges ,of the keys, sothat'on tilting the latter, the plates I will be taken along, to eject the cows. The

length of theshort' slots should be suchthat there is 7, provided a sufficient clearance between their rear perimeters and the rear edges of the unoperated keys to hold the,

latter in an inert position when the plates are advanced by the action of keys of a different denomination. The long. slots 52 ex- 44 operatively engages emsw .t-endtosuclr' a distance in front and back of their respective keys,gthat the latter have a free play therein without coming into contact with either the front or rear perimeters of theslots. I Or 'in other words, there is in all positions of the'keys a clearance between "such [keys'and the plates'wherever the latter are provided with the long slots. \Vhile plates 22-29 are advanced bymeans of the keys 44, they are retracted by coiled springs 53 hooked at one end to frame 10, as at while at their other end they are adjustably secured to,theirrespective plates by means of racks #55 that permit the tension of the springs to be adjusted. As has been stated,

the correlatioirof the parts is such, that each key will take along such specific plate or plates only, as'will deliver the change indicated upon'the 'fingeriece of suclrkey. It has also been setfortli'that-'this'taking along efi'ek'rted by the engagement of the heYSWVltll the perlmeters' ofthe short slots while the keys will more idly'within the long slots key actuates solely plate 23 ,of the lower pennyejector 33; the two cent key actuates plate 24 of the two cent ejector 34; the

plates 23 and 24," and the four cent-key act ates, simultaneously, plates 22, 23 and 2t. The fifteen cent key 44" will notuate the lite cent plate 25 and the ten cent plate 27, while it wiltp'a'ss loosely through all of the other plates. The thirty five cent key 44? will en age the ten .centplate 27 and the twentyve c'entplate 23.

To illustrate: The one cent three cent key 'act-uates, simultaneously, I

The fifty-five-cent key44 will actuate the fivecent plate 25 and the fiftycent'plate'29. In like manner. the twenty cent key will engage, both plates 26, 27 to simultaneously discharge two "dimes, while the dollar key will simultaneously discharge one" nickel,
